LESTER W. MALLORY, OF IONE, OREGON RULING-PEN.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed July 18, 1907. Serial No. 384,385.

To all whom it may concern:

Be it known that I, LESTER W. MALLORY, a citizen of the United States, residing at Ione, in the county of Morrow and State of Oregon, have invented new and useful Improvements in Ruling-Pens, of which the following is a specification.

This invention relates to What are commonly known as ruling pens. In pens of this character the ink therein from a variety of causes will frequently not flow freely and draftsmen adopt various expedients to overcome this defect, none of which are wholly satisfactory as by the most usual of them, the fingers become soiled. By virtue of my invention I can in an efiective and easy manner by positive means, cause the flow of the ink in such a pen should its feed be arrested.

In the drawings accompanying and forming a part of this specification I have shown, for the purpose of indicating the advantages of my invention, one simple form of embodiment thereof which, primarily to enable those skilled in the art to practice said invention, will be disclosed in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

Referring to said drawings: Figures 1 and 2 are elevations at right angles to each other of a ruling pen involving my invention. Fig. 3 is a view corresponding to Fig. 1, of the blades of the pen opened. Fig. 4 is a view corresponding to Fig. 2,' with the feed-blade in a laterally shifted position. Fig. 5 is a perspective view of the blade portion of the pen with the blades thereof separated. Fig. 6 is a similar view of the feed-blade. Fig. 7 is a like view of a bolt. Fig. 8 is a vertical sectional view, and Fig. 9 a horizontal sectional view of the pen, the sections being in proximity to the bolt to which reference was just made. 1

It will be seen that the scale of Figs. 5 to 9, inclusive, is much larger than that of Figs. 1 to 4, inclusive.

Throughout these several figures like characters of reference denote like parts.

The handle of my improved ruling pen is designated by 2 and associated therewith is a stationary blade as 3 and a movable blade as 4 which,.except as to the particulars hereinafter set forth, are constructed and operated in the well-known manner.

In the present case, when the flow of the ink is arrested, I overcome this difficulty by positive means movably connected with .the pen and, although the same may be of any desirable character, I prefer to provide a feed-blade such as that denoted in a general'way by 5 for this purpose. I might also state that I sometimes term this part 5 a flow-blade. The blade 5 is preferably mounted between the pen blades 3 and 4 and is capable of longitudinal movement with respect thereto, so that, should the fiow of the ink be arrested, the blade 5 can be moved in an endwise direction to cause the flow of the ink.

The blade 5 includes in its make-up a body portion as 6 which is which has a longitudin slot as 7 through which a bolt, such as that denoted in a general way by 8, passes. When the blade 5 is in its working position it lies against the adjacent face of the stationary blade 3. The body 6 is represented as having above and below the slot 7 and at opposite sides thereof the bent lugs or ears 9 which are adapted to overlie the lateral portions of the blade 3 when the blade 5 is in its normal position. These bent lugs or ears guide the feed or flowblade 5 during its working or advancing and retracting movements. The bolt 8 is provided at one endthereof with a flattened portion 10 and at the other'end with the customary thumb-nut 11. This flattened portion 10 is disposed in the slot 7, as clearly shown in Fig. 8, and it extends through a segmental slot as 12 in the stationary blade 3, said slot having at one end of its upper side an oifset or aperture as 13 the pur ose of which will hereinafter be evident. T e fiattened portion 10 has on the upper side there:

Figs. 1, 8, and 9, t e nut 11 at this time being turned home, the flattened portion 10 being in the segmental slot 12 and also in the elongated slot 7. The stop or fin will also be against the solid portion of the pen blade 3 at a point relatively remote from the offset 13. When this condition is present the blade 5 can be moved freely in an endwise or longitudinal direction and, of course, longitudinally with respect to the two blades 3 and 4. The body 6 is narrowed near its lower end on downwardly-converging lines as at 16, and from said narrowed portion 16 there extends preferably flat and a the deflected portion 17 from which the point 18 projects. Said point 18' constitutes the working part of the feed or flow-blade 5. It will be clear that the point 18 extends toward the outer ends of the two pen blades 3 and 4, but in the present case, it extends short of said ends. At the upper end of the body portion there is shown as located a lug as 19 to which the lower end of a spring as 20 is connected, the upper end of said spring being united with a fixed part of the pen. The function of this spring is to hold the feed or flow-blade 5 in its retracted position and to also return it to such position after the same has been advanced for-the purpose of promoting the flow of the ink. In Fig. 1, for instance, the blade 5 is in its upper or retracted position. It will be assumed that, when it is in such position, the ink refuses to flow. To overcome this difliculty the blade 5 is moved downward so as to project the forward or lower end of the point 18 beyond the points of the pen-blades 3 and 4 by virtue of which the ink will be caused to flow freely. If the said pen-blades are resting on paper the feed blade will be advanced into contact with such paper to obtain the desired object. To facilitate the operation of the feed or flowblade 5 it may be provided at a convenient place, such as near the lower end and at one side thereof, with a laterallyextendingfingerpiece or projection 21 which, as will be obvious, owing to its location, is in easy reach of a finger of the hand of the user of the pen, for the purpose of moving the blade 5 down ward to eifect the function for which it is intended. As soon as the operator removes his finger from the projection 21 the blade 5 is promptly returned to its original position by the power of the spring 20.

It is necessary at times to clean the pen, and this result can be attained without the necessity of separating the parts thereof. To accomplish such object the blade 5 is swung laterally as shown for instance in Fig. 4, the bolt 8 turning therewith, and the movement continuing until the fin or stop 14 registers with or is opposite the offset or aperture 13. When this condition ensues the blade 4 can be swung away from the blade 3, the fin 14 entering the slot and the movement being continued if necessary until the stop 14 strikes the blade 3. The blade 4 therefore can be readily separated from the blade 3. It will, of course, be necessary to unscrew the nut 11 to efl ect such separation.

The upper end of the slot 7 has an enlargement or circular portion 7 to receive the shank or stem of the bolt 8 whereby the parts can be properly assembled. The movable blade 4 may be of any desirable type.
